  • 175. Of three numbers, the third is twice the second and the second is 4 times the first. If their average is 78, the smallest of the three numbers is:
   A.) 18
   B.) 21
   C.) 17
   D.) 15

Answer: Option 'A'

Let first number be x. 
So,2nd number = 4x and 3rd number = 8x.
Given average = 78 So,x + 4x + 8x = 78 × 3 = 234. => 13x = 234 => x = 234/13
Hence, Smallest Number x=18.
